STEAM-TRAP.

SPECIFICATION forming part of Letters Patent No. 363,243, dated May 17, 1887, Application filed April 3, 1386. Renewed November 15, 1836. Serial No. 218,919. (No model.)

To all whom it may concern.-

Be it known that I, J OIIN KANE, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Steam-Traps, of which the following is a specification.

My invention has reference to steam-traps; and it consists in certain improvements, all of which are fully set forth in the following specification, and shown in the accompanying drawing, which forms part thereof.

. In carrying out my invention I connect a vertical cylinder at top and bottom, by means of flexible pipes, to a steam or condensed water-supply and a water-discharge, the latter of which is provided with a suitable valve. The cylinder is supported by a weighted lever, and when empty the said lever holds it in a raised position,- but when sufficiently full to overcome the counter-weight the lever is oscillated andthe water-cylinder descends. Simultaneously with said latter action the dischargevalve is opened and the water from the trap is discharged, the action of gravity being assisted by the pressure of steam above the water. The lever has its movements made adjustable by means of cam or eccentric shaped stops, which may be adjusted to limit the throw of the said lever, and also somewhat change its relative position of movement. This lever is provided with an auxiliary weight, which moves with the oscillation of the lever and adds to or reduces the counter-balance, and thereby aids to hold the trap in a raised position until full, and after said trap has been tripped to hold it in its depressed condition until nearly all of the water has been discharged therefrom. A steam-trap of this nature operates automatically, and may be used for discharging condensed water from steam-heating apparatus or exposed steam-pipes without allowing the passage of steam.

The object of myinvention is to construct a trap in a simple and cheap manner, and so that it can be adj usted and insured to work under all conditions, and to discharge a maximum quantity of water with a minimum number of movements, thereby reducing the wear upon the working parts and increasing the life of the machine.

In the drawing is shown a front elevation of a steam-trap embodying my improvements, one of its positions being shown in solid lines and the other or discharging position being shown in dotted lines.

A is the hollow receiving-vessel, and is connected at the top by a flexible pipe, 13, with the steam and water supply D, and at the bottom by a flexible pipe, 0, with the dischargepipe F, which is furnished with a valve, E. This connection allows the vessel Ato be raised or lowered, the said pipes 13 and (J acting as parallel bars and always retaining the vessel in a vertical position.

G is a water-gage, to indicate the amount of water in the vessel A. The vessel A is suspended from the lever H, which is pivoted at h to a fulcrumplate, J, and its movement is limited and its position of movement controlled by adjustable cam or eccentric shaped stops K, which may be clamped in a rigid position by bolts or screws 70. I

The supporting-lever H is counterweighted at I, so that when the vessel A is empty the weight I depresses its end of the lever and raises the vessel to the position shown in solid lines; but when the vessel is full the water in it overbalances the weight I and oscillates the lever H, causing the vessel to assume the position indicated in dotted lines. iary weight M is suspended to aplate, L, which is adjustably secured to the lever H, and in the oscillations said auxiliary weight approaches or recedes from the fulcrum h of the lever, thereby assisting or opposing the action of the counter-weight I. The object of this is to retain the vessel A in its raised position until completely full, and then cause it to remain in its depressed position until it is almost empty. This auxiliary weight and its support are made adjustable, whereby the foregoing results may be increased or decreased, as desired. A lever, H, is connected by a rod, N, with the valve-lever P through a pin, 1), and slot 1%, the former working in the latter. If desired, however, the lever H might be positively connected, so that the instant the vessel A commenced to descend the valve E would be opened.

The movements are automatic, and the discharge never takcs place until the vessel A is The auxil not limit myself to the details thereof, as they may be modified in various Ways without departing from my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, i's

1. In a steam-trap, the receiving-vessel and its connecting supply and discharge pipes, in combination with the supporting pivoted and counterweighted lever, a valve in the discharge-pipe, and a slotand-pin connection between the said valve and lever, whereby the movement of the lever opens the valve at any desired position of its oscillation.

2. In a steam-trap, the receiving-vessel and its connecting supply and discharge pipes, in combination with the supporting pivoted and counterweighted lever, and adjustable cam or eccentric shaped stops to limit and adjust the throw of the lever, substantially as and a for the purpose specified.

8. In a steam-trap, the receivingvessel and its connecting supply and discharge pipes, in combination with the supporting pivoted and counterweighted lever, adj ustable stops to limit-and adjust the throw of the lever, and an auxiliary weight suspended to the supporting-lever'to assist in retaining it in its extreme positions, substantially as and for the purpose specified.

'4. In a steam-trap, the receiving-vessel and its connecting supply and discharge pipes, in combination with the supporting pivoted and counterweighted lever, adjustable stops to limit and adjust the throw of the lever, a valve in the discharge-pipe, a connection with the supporting-lever to operate said valve, and an auxiliary weight suspended to the'supporting-lever to assist in retaining it inits extreme positions, substantially as and for the purpose specified. Y

5. In a steam-trap, the receiving-vessel and its connecting supply and discharge pipes, in

combination with the supporting pivoted and counterweighted lever, adjustable stops to limit and adjust the throw ofthe lever, a valve in the discharge-pipe, a connection with the supporting-lever to operate said valve, and an adjustable auxiliary weight suspended to the supporting-lever to assist in retaining it in its extreme positions, substantially as and for the purpose specified.

6. In a steam-trap, the receiving-vessel and its connecting supply and discharge pipes, in combination with the supporting pivoted and counterweighted lever, adjustable stops to limit and adjust the throw of the lever, a valve in the discharge-pipe, and a connection between said valve and supporting-lever, subtantially as andfor the purpose specified.

7. The combination of vessel A with flexible supply and discharge pipes B O, suspending lever H having counter-weight I, valve E .in the discharge-pipe, lever P to operate the valve, and rod N, connected with the lever H and having a slotted connection with lever P, substantially as and for the purpose specified.

8. The combination of vessel A with flexible supply and discharge pipes B C, suspendinglever H, having counter-weight I,valve E in the discharge-pipe, lever to operate the valve, rod N, connected with the lever Hand having a slotted connection with lever P, and 1 adjustable stops K for lever H, substantially as and for the purpose specified.

9. The combination of vesselAwith flexible supply and discharge pipes 13 O, suspending lever H, having counter-Weight I, valve E inthe discharge-pipe, lever P to operate th'e valve, rod N, connected with the lever H and having-a slotted connection with lever 1?, ad j ustable stops K for lever H, adjustable support L, secured to lever H, and auxiliary weight M, suspended therefrom, substantially as and for the purpose specified.
